Fender Super Twin

Hi all,

the Fender " Super Twin " has to be my least favourite Fender model.

This week, one came in that had been modified, butchered and totally buggered.

The list of things wrong was staggering:

1. No AC fuse and foil inside the holder.

1. AC switch broken.

2. Standby switch broken.

1. OP tranny loose.

2. Two 6L6s visibly burnt on bases and glass.

1. Two 6L6s missing ( out of six ).

2. Two diodes in main bridge short circuit.

1. Bias filter electro open.

2. Bias feed resistors changed from 33k to 330 kohms.

1. Hum balance pot burnt out.

2. Negative feed back resistor changed from 820ohms to 1Mohm.

1. UL connection on 6L6 screens removed and new screen supply circuit fitted badly.

2. All filter electros 36 years old.

1. Main filter electros 100uF each instead of specified 220uF each.

2. Chassis and cabinet dirty and speaker bolts all loose.

The only good thing and what made the amp worth doing was that the two 12 inch speakers were 75 watt Fanes in good condition.
